Inrush current limiting is not just to protect the power switch or other internal components. It is needed to prevent transients on your AC line from damaging other equipment. I watched our nearby big screen TV power supply fail as I turned on my computer, which had particularly bad inrush current (enough to make the lights in the room flicker). Troubleshooting revealed the TV power supply switching chip had failed.
As we usually have little control over our AC line regulation or the susceptibility of other devices, keeping AC line current transients within reasonable limits is a good idea.
That doesn't make much sense to me. For many years, computers have all used power factor corrected switchmode power supplies that have very little inrush current, and won't even meet international compatibility standards if they create a line transient.
Re huge inrush currents and line transients, I doubt anything is as bad as large electric motors are. My central A/C system consumes 40A at 240V and uses a remote contactor to start the compressor and creates such a huge line sag that when it starts the lights in the house can "blink" and it's never damaged anything. Nor have my 1-1/2 HP pool and spa pumps, or large Kirby vacuum cleaner, or...really anything.
